Best way to store my fertile hatching eggs

Just a quick question,
I have a few laying hens in my coop, of which only 2 are currently laying. They happen to be my SLW's (BR's have stopped laying for the time being). I have one SLW rooster as well, so for now it is a pretty easy guess as to what I would be getting out of an eg if I put it into the incubator. My question is, since I am only getting 2 eggs a day, I would obviously like to store them until I get a reasonable amount worth incubating, so what is the best way to store them, and for how long can I store them that way? I have heard putting them in the refrigerator for up to a week works? Anybody have any suggestions?

Me too.... in fact, I have eggs, fertile eggs that have been refrigerated for several weeks in my frige and my question is: can I put these in an incubator and expect anything good to come of it?? I just bought a new incubator which is here in a few days and, I'm getting Favarolle eggs everyday and they are the focus of my "hatching" intentions but amassing 30+ eggs takes some time, so frige or no?

Also...I've read a lot of threads that say collect eggs for 7 days, and then incubate. The fertility drops after 1 week of sitting, and drops drastically after 2 weeks. Of course you will have some that say they collect for several weeks and then incubate. I'm just trying to offer info that I read on here.
